Knocking on doors is tedious in Upper Mount Bethel, a sleepy rural township of almost 7,000. But as dusk falls on Friday, Amy Cozze’s minivan pulls up to a wooden home, and she hops out to meet another voter.

The 35-year-old baker and breast cancer survivor is trying to flip the seat from red to blue while facing an entrenched incumbent. Rep. Joe Emrick (R-Northampton) has served since winning in 2010, during the Tea Party movement that took over Congress and state Houses across the country. Since then, no Democrat has broken 40 percent of the vote again him.

But Cozze is one of the Democrats running to try and win power back, hoping that enthusiasm, the top of the ballot, and some door-to-door coaxing of ticket splitting Democrats can bring results, while Republicans look to leverage a growing economy to hold their ground.
